Chav pipelines ua lub hauv paus nruab nrab rau kev lag luam thermal zog thauj. Hauv Suav teb, tau tsav los ntawm "Dual Carbon" cov hom phiaj, tau muaj kev nce siab hauv cov haujlwm uas cuam tshuam nrog kev ua kom huv si ntawm cheeb tsam cua sov, qhov chaw nruab nrab ntawm cov chaw ua haujlwm rau cov chaw ua lag luam, thiab loj - nplai refining thiab thee - tshuaj ua haujlwm. Yog li ntawd, qhov kev thov rau siab -kub cov kav dej txuas ntxiv nce ntxiv. Txawm li cas los xij, chav dej sib txawv ntawm cov dej kub ntau heev - nws muaj qhov kub thiab txias dua, siab dua, thiab ntau dua thermal expansion dynamics. Cov yam tseem ceeb no ua rau cov kev cai nruj rau txhua theem ntawm cov kav dej, los ntawm kev tsim mus rau kev tsim kho. Xaiv ib qhov project-cov chaw tsim khoom tsim nrog cov kws tshaj lij kev sib sib zog nqus feem ntau yog qhov kev txiav txim siab seb lub raj xa dej puas ua haujlwm nyab xeeb, ua tau zoo, thiab muaj kev ntseeg siab rau lub sijhawm ntev.
Peb Qhov Tseem Ceeb Ntawm Qhov Sib Txawv: Vim Li Cas Cov Pipelines Chav Ua Haujlwm Ntau Dua?
Piv nrog rau cov pa cua sov cov kav dej, cov raj xa hluav taws xob insulated muaj peb qhov kev sib tw tseem ceeb:
Thermal Bridge Management. Nyob rau hauv cov kav dej siv hluav taws xob, cov vuam txuas ncaj qha mus rau cov khoom thauj steel yeeb nkab tsim "thermal choj," uas tso cai rau cov cua sov los ntawm kev txhawb nqa hlau. Qhov no tsis tsuas yog txo cov kev thauj mus los tab sis kuj ua rau muaj kev pheej hmoo kub hnyiab rau cov neeg ua haujlwm. High-cov khoom lag luam zoo feem ntau yog siv cov txheej txheem sab hauv lossis sab nraud nrog rau qis- thermal- kev txhawb nqa zawv zawg kom txo tau qhov cuam tshuam ntawm tus choj thermal.
Moisture Venting Design. Yog tias cov dej nkag mus rau hauv cov txheej txheem rwb thaiv tsev ntawm ib qho ncaj qha - faus cov kav dej, qhov tshwm sim los ntawm kev rwb thaiv tsev tsis ua hauj lwm mus rau qhov hnyav ntawm cov txheej txheem los yog cov yeeb nkab rupture. Cov kav dej ntub dej yog qhov tseem ceeb rau kev daws qhov teeb meem no; lawv tshem tawm cov dej noo los ntawm cov txheej rwb thaiv tsev thaum lub raj xa dej sov- nce theem- kom ntseeg tau tias cov khoom siv rwb thaiv tsev ua tiav nws cov qauv thermal conductivity-thaum tseem ua hauj lwm raws li cov teeb liab conduits rau kev kuaj pom. Cov kws tshaj lij muab cov chaw tso pa tawm ntawm cov ntsiab lus ntawm cov kav xa dej tsawg tsawg (ze li kev txhawb nqa ruaj khov) thiab siv cov rwb thaiv tsev nruj thiab tiv thaiv- kev kho corrosion (xws li "tsib- txheej txheej thiab peb- txheej ntaub" txheej txheem).
Txias Tightening thiab Thermal Compensation. Thaum lub sij hawm pib, cov cab kuj steel yeeb nkab heats li ntawm ambient kub mus rau 350 degree, ua rau muaj ntau thermal expansion. Cov txheej txheem txias txias tso cai rau ua ntej- teeb tsa kev hloov chaw thaum lub sijhawm teeb tsa kom txo qis kev ua haujlwm; qhov no, ua ke nrog kev them nyiaj ntuj tsim nyog (siv L-zoo li lossis Z-zoo li tus khoov) lossis cov pob qij txha nthuav dav, ua kom muaj kev nyab xeeb ntawm cov kav dej.
Plaub qhov tseem ceeb rau kev xaiv ib lub Tuam Txhab Tuam Txhab Suav
Ib tug txhim khu kev qha suav cov yeeb nkab xa khoom yuav tsum muaj cov peev txheej hauv qab no:
Kev Tsim Nyog thiab Cov Qauv Txuj Ci. Muaj daim ntawv tso cai tsim khoom tshwj xeeb; cov khoom nruj me ntsis ua raws li cov qauv xws li CJJ/T 104-2014 (*Technical Specification for Direct-Buried Steam Pipelines for Urban Heating*) thiab CJ/T 246-2018. Cov neeg muab khoom muaj peev xwm koom nrog hauv cov qauv tsim qauv feem ntau ua kom pom tseeb dua ntawm cov ntsiab lus kev paub.
Kev loj hlob ntawm kev tsim qauv. Muaj peev xwm muab cov lus pom zoo zoo- xws li sab hauv - zawv zawg lossis sab nraud - zawv zawg tshuab - haum rau cov xwm txheej tshwj xeeb, nrog rau cov ntaub ntawv suav thiab cov duab kos kom ntxaws, tsis yog tsuas yog muab tawm ntawm -- cov khoom txee.
Integrated noo noo venting thiab saib xyuas systems. Cov kav dej ntub dej, cov kav dej condensate, thiab cov tshuab nqus dej yuav tsum tau muab los ua kev daws teeb meem ntau dua li cov khoom lag luam. Cov kev xaiv ntse, xws li fiber ntau- kho qhov muag saib xyuas, tau nce zuj zus los ua tus qauv rau cov haujlwm loj -.
Ntawm - qhov chaw muaj peev xwm ua haujlwm. Cov txheej txheem tseem ceeb-xws li kev sib koom ua ke, kev sib txuas ntawm cov kav dej noo, thiab kev sib txuas ntawm cov kev txhawb nqa ruaj khov- yuav tsum tau nyob ntawm - qhov kev taw qhia los ntawm cov neeg ua haujlwm paub txog; txwv tsis pub, muaj teeb meem kev nyab xeeb tseem ceeb yuav tshwm sim.
Lub sij hawm xa khoom thiab kev ruaj ntseg muaj peev xwm
Cov kav dej xa hluav taws xob feem ntau yog cov phiaj xwm tseem ceeb txhua xyoo rau tsoomfwv lossis cov lag luam loj, thov kom ua raws li cov sijhawm xa khoom. Sab saum toj -tier Suav cov kav dej xa hluav taws xob ua haujlwm ntau yam "steel-casing-steel" cov kab ntau lawm thiab ruaj ntseg ua ntej cov khoom siv tseem ceeb (xws li seamless steel kav thiab tiv thaiv- coatings coatings) los xyuas kom meej cov sij hawm ntau lawm raws li kev pom zoo. Nrog lub peev xwm thauj khoom txhua hnub ruaj khov ntawm ntau tshaj li ib puas lub tsheb thauj khoom, lawv tuaj yeem tswj xyuas kev tsim khoom thoob plaws ntau lub chaw hauv cheeb tsam kom lav cov khoom siv txuas ntxiv rau cov haujlwm hauv thaj chaw deb.
Xingbang Pipeline: 30 Xyoo Tsom Ntsig Rau Chav Pipelines
Tangshan Xingbang Pipeline Engineering Equipment Co., Ltd. tau tsim nyob rau hauv 1995. Nws yog ib lub koom haum pab txhawb rau lub teb chaws cov qauv xws li GB/T 29047-2012 thiab tuav ob qho tib si Special Equipment Manufacturing License thiab EU CE certification. Lub tuam txhab muaj ntau tshaj 140 lub teb chaws patents thiab tau sau cov kev txawj ntse nyob rau hauv cov cheeb tsam xws li chav pipeline ya raws venting, thermal choj mitigation, thiab insulated tsau kev txhawb nqa.
Lub tuam txhab muaj peev xwm tsim tau txhua xyoo ntawm 1,000 mais ntawm DN20-DN1200mm "steel-casing-steel" steam insulation piping, nrog rau cov khoom sib xws (lub luj tshib, tees, condensate drainage units, thiab kev txhawb nqa ruaj khov) muaj rau ib txhij prefabrication. Nws cov khoom tau raug siv nyob rau hauv txawv teb chaws tej yaam num-xws li huab cua sov- txias cua sov system nyob rau hauv Ulaanbaatar, Mongolia, thiab muaj chaw ua si nyob rau hauv Norway-nrog rau nyob rau hauv ntau lub domestic cua sov trunk networks thiab chav tsev mov tej yaam num rau petrochemical industrial parks.
